Question 1

What is Grok Imagine Extend?

Accepted Answer

Grok Imagine Extend is an xAI model that continues an existing Grok Imagine video generation. You provide a request_id from a previous Grok video and a text prompt; the model appends 6 or 10 seconds of new footage while maintaining visual and audio consistency with the original clip.

Question 2

How much does Grok Imagine Extend cost?

Accepted Answer

Pricing varies by duration and resolution: 6s at 480p costs $0.05 per generation, 6s at 720p costs $0.10, 10s at 480p costs $0.10, and 10s at 720p costs $0.15. All billed pay-per-generation with no subscription required.

Question 3

Can I extend a video more than once?

Accepted Answer

Yes. Each successful extension returns a new request_id. You can use that ID to extend again, chaining extensions to build longer sequences from a single starting clip.

Question 4

What resolutions are supported?

Accepted Answer

Grok Imagine Extend supports 480p for faster, lower-cost generations and 720p for higher-quality output. Choose based on your end-use platform and budget.
